A. A. Borisyak - founder of modern historical geology

Abstract

A. A. Borisyak all his life was an active fighter for the doctrine of continuous development, the evolution of not only the organic world, but also the inorganic. For him, the earth's crust, with all the infinitely diverse phenomena associated with it, lived, changed and developed, as it lives , the countless world of animals and plants that inhabited and inhabits it changes and develops. A. A. Borisyak did extremely much for Soviet geology. He developed the doctrine of the correlative development of the earth's crust and life on it; he developed and applied the doctrine of geosynclines to the territory of the Soviet Union. Of enormous importance is the introduction into geological and paleontological work of the paleogeographical method and its most important part - the doctrine of facies. These three doctrines - the doctrine of the correlative development of earth and life, the doctrine of geosynclines and the doctrine of facies - underlie most of our work, both theoretical and practical. This is an unforgettable merit of A. A. Borisyak.
